Abstract (en)

[origin: EP0316836A2] A surface-acoustic-wave device consists of a surface-acoustic-wave filter with a capacitance (C) connected in parallel between its input (21) and output leads (31). The capacitance improves the attenuation characteristic of the device on the high-frequency side of the center frequency.
